Water treatment flocculation: Which flocculation agent is best?

Polyacrylamides; Polyacrylamide is a polymer-based flocculant that is widely used in the treatment of water, ranging from waste water to drinking water. It is often used as an anionic ¡ª or negatively charged ¡ª flocculant and is popular in industry, thanks to its broad availability and relative safety when in use or in storage.

Natural Versus Synthetic Polymers for Wastewater Treatment - Dober

Coagulation and flocculation are the most widely used approaches for solid and color removal from wastewater. The conventional methods of solid-liquid separation ¡ª such as filtration, sedimentation, centrifugation and flotation ¡ª are not efficient enough to completely remove suspended particles from wastewater.
